Unformatted text preview: -The energy carried by each photon depends on its frequency (color) o E = h f = h c / Î» o Bluer light carries more energy per photon. Light and Matter-We can separate light into its different wavelengths (spectrum).-By studying the spectrum of an object, we can learn its: o Temperature o Composition o Velocity-Each atom has specific energy levels particular to that element.-Elements/molecules have specific â€śfingerprintsâ€ť which enable us to determine composition. Electron orbits-Ground state, Excited state, Ionization Electron energy levels-Electrons cannot have just any energy while orbiting the nucleus.-Only certain energy values are allowed.-Electrons may only gain or lose certain specific amounts of energy.-Each element (atom or ion) has its own distinctive set or pattern of energy levels....
